I guess it depends who you're writing with. I'm not terribly attached to either style, and will pepper internal monologue or fourth-wall breaking pieces into my emotes here and there. So far, no complaints -- if people don't like my RP style, they have the choice of not RPing with me. Actually, more often than not I get whispers from strangers saying my RP made them laugh or smile and that's always nice to hear.
Just do what feels natural, don't use RP as a means to be nasty OOC, and don't assume reactions for other characters. You can say a lot with body language and play with your emotes to decide how much you want to conceal and how much you want to reveal, and that depends entirely on the type of character you write and the kind of scene you are doing. Sometimes it's just easier to say "Marcellain looks perturbed" than typing out four paragraphs about chewing nails and pulling hair in the corner.
